Definitions

  • the invention relates to endless tracks for propelling vehicles operable off-road, such as tracked work vehicles (e.g., construction vehicles, agricultural vehicles, forestry vehicles, etc.).
  • tracked work vehicles e.g., construction vehicles, agricultural vehicles, forestry vehicles, etc.
  • JP2000233775 shows a track for a vehicle with an elastomeric body extending in width direction provided with an embedded central core piece and a groove in the lengthwise direction of the endless track ground engaging surface.
  • US 2004/084962 A1 concerns a track for a vehicle travelling on all terrain, especially those displaying ruts, is formed of an endless longitudinal body displaying a series of longitudinally spaced drive lugs on its inner surface and a series of longitudinally spaced profiles on its outer surface. Each profile displays a height decreasing in value from the center of the body to the outer edge thereof.
  • the body is formed of flexible rubber material and is free of conventional transversally extending reinforcing embedded rods thus providing reduced transverse rigidity to the body and allowing the body to curvingly flex when engage in ruts.
  • EP 1 506 913 A1 discloses a rubber crawler track having an endless rubber belt-shaped rubber crawler track main body formed of a rubber elastic body, etc. and core metal pieces embedded in the rubber crawler track main body at predetermined intervals in a circumferential direction of the rubber crawler track.
  • a high hardness intermediate rubber layer track main body is provided from below at least the ground contacting surface side of an end portion in a length direction (rubber crawler track width direction) of the core metal pieces toward outside the end portion in a width direction of the rubber crawler track.
  • the rubber elastic body of the rubber crawler track main body is formed in a multiply layered structure with at least two or more layers.
  • EP 1 008 509 A1 disclose an elastic flat tread provided with a core fitted to a link or a core fitted to a metallic plate fitted to a link. End parts of the core in the lengthwise direction are bent toward the side not in contact with the ground.
  • US 2003/034690 A1 concerns a elastic crawler shoe comprising a core bar fixed directly or through an iron shoe to crawler belt links, each of which is endlessly coupled, and an elastic body bonded to the core bar so as to cover the core bar, wherein the elastic body has a ground contact face having grooves or incisions.
  • EP 2 119 620 A1 discloses a rubber crawler track comprising: an endless belt-shaped rubber resilient body configuring an endless track; a plurality of protrusions provided protruding from the inner peripheral face of the rubber resilient body at uniform intervals along the circumferential direction thereof; and grooves located at the roots of the protrusions and formed in a wheel-passing face that a wheel follows in motion.
  • Certain off-road vehicles including work vehicles such as construction vehicles (e.g., loaders, bulldozers, excavators, etc.), agricultural vehicles (e.g., harvesters, combines, tractors, etc.) forestry vehicles (e.g., feller-bunchers, tree chippers, knuckleboom loaders, etc.) and military, vehicles (e.g., combat engineering vehicles (CEVs), etc.), are often equipped with endless tracks that enhance their traction and floatation on soft, low friction and/or uneven grounds (e.g., soil, mud, sand, ice, snow, etc.) on which they operate.
  • work vehicles such as construction vehicles (e.g., loaders, bulldozers, excavators, etc.), agricultural vehicles (e.g., harvesters, combines, tractors, etc.) forestry vehicles (e.g., feller-bunchers, tree chippers, knuckleboom loaders, etc.) and military, vehicles (e.g.,
  • One type of endless track comprises a body including elastomeric material (e.g., rubber) in which are embedded rigid cores (e.g., metallic cores) that extend transversally to impart transverse rigidity to the track and that guide or otherwise interact with wheels of the vehicle which face the track's inner side.

  • a problem often encountered with this type of endless track is that, when a lateral edge part of the track impacts an obstacle on the ground (e.g., a curb, a sidewalk, a rock, an abrupt change in ground level, etc.), the track may deform in such a way that some of its elastomeric material in its lateral edge part begins to tear. Such tearing of the track's elastomeric material, which is referred to as "edge-cutting", may cause premature deterioration of the track.
  • sand, rocks, water and/or other undesirable matter may infiltrate the track through the tear and prematurely deteriorate the track (e.g., by leading to a progressive loss of adhesion between the elastomeric material and the cores and/or other components of the track).

Also, the hole 72 i reduces a likelihood of the part 76 of the rubber 38 between the hole 72 i and the cores 44 1 -44 N being sheared against the cores 44 1 -44 N . By relieving stress in the portion 51 of the rubber 38, the hole 72 i protects against tearing of the portion 51 of the rubber 38.
